If you’re comparing solar lighting to traditional wired (AC) lighting costs, it’s easy to focus on the price of a single solar fixture to that of a standard AC fixture and get sticker shock. We see this all the time: someone calls us because it’s too expensive or impractical to run power to a site, then months later they say, “We decided to trench and bring power out instead.” Often, that decision is based on system price, not total project cost, including installation of the grid power, as well as costs over time. Let’s walk through the key pieces so you can make a clear, apples-to-apples decision.
1. System Cost: What You See on the Quote
A complete commercial solar lighting system is much more than simply “a light with a panel.” In most cases, it includes the solar panel, battery storage, charge controller, LED fixture, pole, mounting hardware, and often controls such as dimming, motion sensing, scheduling, etc. Because all of these components work together as one self-contained system, pricing can vary quite a bit.
As of the mid-2020s, a commercial-grade solar lighting system may range from around $1,500 to $3,500 for lower-output applications, from about $3,500 to $7,000 for many mid-range systems, and from $7,000 to $13,000 or more for high-end, decorative, or high-output installations. Costs tend to rise when projects require higher light levels for roadways or large parking areas, when fixtures must meet a specific decorative style, or when the system must perform in demanding conditions such as cold climates, cloudy regions, or coastal environments.
A good quote should clearly explain what is included in the system, such as panel size, battery capacity, fixture output, pole height, and control settings. It should also explain the expected lighting performance, including operating hours and coverage, along with warranty details and any relevant certifications such as UL or DLC. If that information is missing, it becomes much harder to compare products or make a confident decision between solar and wired lighting.
2. Installation Cost: Where Solar Often Wins
Installation is often the point where solar lighting becomes much more competitive, and in some cases significantly less expensive overall.
For a commercial solar light, setting the pole and installing the solar power assembly often costs roughly $500 to $2,500 or more per pole, depending on the site. Soil conditions, foundation requirements, regional labor rates, permitting, inspections, and the type of equipment needed for installation can all affect the final number. One of the biggest advantages of solar is that there is no need to trench for electrical power or extend utility infrastructure to each pole. The system produces and stores its own power at the point of use.
By contrast, traditional AC lighting may use a less expensive fixture, but the fixture is only part of the installation cost. You also have to bring power to it, which may require trenching, conduit, wiring, electrical terminations, panel work, transformers, backfilling, and surface restoration. In many projects, trenching alone can range from just a few dollars to more than $20 per linear foot, depending on the trench depth, the surface material, and local labor conditions. If the job requires cutting and patching asphalt or concrete, crossing sidewalks or drive lanes, or navigating around existing underground utilities, the total installation cost can rise quickly.
When those infrastructure costs are included, solar often becomes more cost-effective, especially in remote locations, large or spread-out properties, or places where existing electrical service is limited or far away.
3. Infrastructure Challenges: Parking Lots, Roads, and Retrofits
One of the most overlooked costs in wired lighting projects is the challenge of working around existing infrastructure.
For example, if a new light is needed in the middle of a parking lot and there is no power at that exact location, the project may require saw-cutting pavement, trenching across traffic areas, installing conduit and conductors, and then restoring the surface afterward. That process can add significant labor, increase project timelines, and create disruption for customers, tenants, employees, or visitors.
Solar lighting avoids much of that disruption because each pole is self-powered. That means you can place lighting where it is needed without tearing into finished surfaces or extending underground electrical lines. In many retrofit situations, this can lead to a faster installation, lower restoration costs, and much less interruption to normal site operations. It also gives property owners more flexibility if layouts, traffic patterns, or lighting needs change over time.
4. Project Cost: Look at the Whole Picture, Not Just One Fixture
To make a fair comparison, it’s important to think in terms of total project cost, not just the cost of one fixture.
A full project budget includes the equipment itself, but it also includes electrical infrastructure for AC systems, site restoration, labor, permitting, inspections, equipment rental, and long-term operating costs. When all of those pieces are added together, the lowest fixture price does not always lead to the lowest overall project cost.
Solar is often especially competitive on projects where there is no existing power, where the lighting locations are far from available service, where the owner wants to reduce environmental impact, or where major trenching and site disruption would be expensive. In those situations, the total cost of a solar lighting project can be very close to, or even lower than, a conventional wired installation.
On the other hand, wired AC lighting can still be the less expensive upfront option if power already exists exactly where it is needed, the site has sufficient electrical capacity, and no major upgrades or trenching are required. That is why comparing full project quotes side by side is so important. Looking only at “price per fixture” rarely tells the whole story.
5. Long-Term Cost: Energy, Maintenance, and Lifespan
Many buyers focus on the upfront installed cost and do not spend enough time evaluating what the system will cost to own over the next 10, 15, or 20 years.
With solar lighting, there is no monthly electric bill tied to the light fixtures themselves, which can be a major advantage in areas with high utility rates. With wired AC lighting, energy costs continue for the entire life of the system, and those costs depend on local electricity prices, operating schedules, and fixture efficiency. Even highly efficient LED lighting still creates an ongoing utility expense when it is powered from the grid.
Maintenance also matters. A properly designed commercial solar lighting system using quality components can provide many years of reliable service. LED fixtures often last 50,000 to 100,000 hours or more, solar panels commonly carry 20 to 25 year performance warranties, and modern based battery systems may be designed to last 5 to 10 years depending on system sizing, usage, and environmental conditions. In many cases, the primary recurring cost is battery replacement at predictable intervals.
Wired lighting systems have their own ongoing costs as well. These may include monthly utility charges, possible connection fees, repairs to underground electrical infrastructure, and damage related to surges, outages, or line faults. Depending on the project, a full life-cycle cost analysis may show that solar is very competitive, especially when energy savings and reduced infrastructure maintenance are taken into account over time.
6. Incentives, Tax Credits, and Funding Opportunities
Another factor that can significantly affect project economics is the availability of financial incentives.
Depending on your location and the details of your installation, you may qualify for federal tax credits, state or local incentives, utility rebates, or grants that support renewable energy, sustainability, or efficiency improvements. In the United States, some projects may benefit from solar-related tax incentives, while municipalities, nonprofits, and certain commercial projects may also have access to funding programs that reduce upfront costs.
To research current incentive opportunities in the U.S., you can visit the Database of State Incentives for Renewables & Efficiency at https://www.dsireusa.org/ and the U.S. Department of Energy at https://www.energy.gov/. Because programs change over time, it is always a good idea to verify current eligibility before making a final financial comparison.
7. How to Compare Solar vs. Wired Lighting for Your Project
If you are trying to decide between solar and wired lighting, the best approach is to gather complete information for both options. That means looking at the total installed cost, including trenching, wiring, site restoration, and any required electrical upgrades for AC lighting. It also means estimating the long-term energy cost of a wired system, reviewing expected maintenance and replacement schedules, and identifying any available incentives or tax benefits.
It is also helpful to consider non-financial factors that can still affect the value of the project. These may include how much disruption the installation will cause, the environmental impact of the system, the flexibility to add or relocate lighting in the future, and the resilience of the lighting during grid outages. Once all of that information is gathered, you can compare upfront cost, long-term ownership cost, and potential payback in a much more meaningful way.
This gives you a clearer and more accurate picture than simply comparing the initial price of one light to another.
Key Takeaway
Yes, solar lighting can come with some initial sticker shock if you only look at the system price. But when you include installation and infrastructure costs, consider energy and maintenance over the life of the system, and factor in incentives and sustainability goals, solar often becomes a very competitive and sometimes more economical solution over the long term.
